Hi, I'm trying to connect our Alcatel OminPCX phone system (192.168.100.235) to 3CX (192.168.100.194) as part of a trial. We don't have SIP trunks on the alcatel system but we do have SIP clients. I've created a new extension and added the connection details as a generic VoIP provider. Registration is OK and when I call this new extension (621) via an alcatel phone it rings a phone on 3CX perfectly OK. But when making a call from the 3CX extension ([email protected]) to an alcatel extension (611) nothing happens, just silence. I know the routes and rules are all OK and below is a section of the log file, can anyone help?

What outbound rules do you have on the 3CX Phone System?
 
The call looks to be routing through OK but what happens later? The start and end of the log shows the same hour, minute, second, so where is the log after a "timeout" period when the call fails?

Have you used Wireshark to see what is sent, and if there is any response from the Alcatel PBX?
 
After about 20 seconds the call drops so you get a hang up tone, data below is the wireshark capture and below that is the whole log...

I've done a port mirror of the network interface for the phone system and performed a wireshark there too, all seems OK and the phone system is responding to the call as far as I can see, there's lots of INVITE's, a REGISTER and more INVITE's, not sure why it isn't working.
 
Does the alcatel have a firewall blocking any traffic/ports?

Do you see the "rejected" reason in other call logs to the PBX? Are there logs in the Omni PBX to show what is going on with a call?
 
The Alcatel has no firewalls between itself and the 3CX and always works fine with any SIP device such as X-lite or Aastra phone. Not sure if there are logs we can get to on the Alcatel PBX but I will find out.

There is no obvious logging I can find, unless someone can point me in the right direction!
 
I would use Wireshark and compare a call attempt from 3CX with a call from a set (perhaps an ATA if you have one handy) using the same extension number. Take note of any differences, even in the initial registration.

This just set-up as a Generic trunk, have you tried using a bridge trunk (slave)?
 
We did try comparing the Wireshark traces of a device that worked compared to one that didn't and although there were small differences there was nothing obvious that jumped out as being the problem. We'll try this again and maybe from a software client on the 3CX server as the comparison too. Our phone system provider have given us a quote for one of their engineers to visit and help with the diagnostics so we may have to take them up on this.

Yes this is setup as a generic VoIP provider not a trunk, the trunk just wouldn't work at all in either direction.
 
We might be getting somewhere, comparing a phone that works to the phone system that doesn't it appears as though 3CX may be trying to connect to the wrong port on the Alcatel system as in the invite request it has this...

User Datagram Protocol, Src Port: sip-tls (5061), Dst Port: 65471 (65471)

Is there a way to force it to 5060?
 
OK, during registration with the Alcatel system this port 65471 appears (maybe NAT?) and I'm sure this is causing the issue. Is there any way to force registration to use port 5060, maybe using custom values in the outbound call? This also comes up in the SIP invites.

User Datagram Protocol, Src Port: sip (5060), Dst Port: 65471 (65471)
 
In the 3CX settings for the generic trunk you created, there should be a setting to tell 3CX the port to use at the far end (SIP Server Port). While most providers will use 5060 as a default, some don't so the ability to "customize" has to be there.
 
Try to set side trunk 3cx
Contact user part = originator caller id
 
We've got it working, in the end we have set up Gateways for outgoing calls (Had to un-tick 'Only Authenticated incoming calls' on the Alcatel system to get it to work too). We set the registration to 'Do not require' and we can now make outgoing calls only via these Gateways. We then set up Providers and these were used for incoming calls only.

It's a bit messy and you have to setup a lot of outbound rules but it's working now it allows us to test the 3CX system alongside our Alcatel Omnipcx which is what we wanted to achieve.

Thank you all for your help.
 
Glad you got it working. Unfortunately, integrating two PBX's, other than an interconnecting trunk for basic calls, is cumbersome at best, and a logistic nightmare at worst.

If the situation allows, and, of course, not all do, it's best to set-up a separate system using PSTN "test numbers", with VoIP trunking, or a gateway, that can then be integrated into in the final deployment.
